thats a pretty horrible description of the problem.

take off the air box and turn the ignition switch ON, the ECU automatically drives the subthrottle valve
from fully closed position to fully opened position.(these are the top buterfly on your throtle bodies) The ECU memorizes these positions and turns back the subthrottle valve to the original point to confirm the subthroltle valve idling voltage.

if the subthrotle valve don't open fully then your problem would be the subthrottle actuator that needs to be changed...

is that the part bolted on to the tps?
